| ...r on carrion. Their larvae feed parasitically on all kinds of larvae, pupae and adult insects. This includes caterpillars, beetles (larvae and adults) and the larvae of various Diptera and arthropods. The larvae of the tachina flies enter their host animals in different ways. Firstly through ingestion of their eggs, secondly through oviposition directly on the host animal, or thirdly through the hatched larvae’s direct entry into the host animal. Usually the host animals die before the larvae’s development is complete. The pupation of the larvae usually occurs outside the host animal.
Since the larvae of many tachina flies kill pests, they are very welcome in the agriculture and forestry industry. | | |

Egg laying takes place on host animals, most commonly on hoofed mammals. The larvae always live parasitically in the interior of the host animals (endoparasites). Many species choose specific animals as the host - which body orifice of the host animal is chosen for egg laying also depends on the species. The hatching maggots (larvae) develop accordingly in the nasal mucous membrane, the throat or beneath the skin (subcutis) of their host animals. Egg laying can be a risky business for some females as the larvae hatch very fast and can attack their own mothers.

...ery fast and can attack their own mothers.
The approach of Bot flies can cause panic reactions in in cattle which often sustain severe injuries by running away into fences or barbed wire. The migration and development of larvae inside the host animals inevitably leads to illness and sometimes to the host animals’ death. The larvaes’ stay in the host animals can last as long as several months. In their last larval stage the maggots leave the host animal and fall down to the soil to pupate.

| | Females lay their eggs on sitting or slow flying host animals, especially on bees, bumblebees, wasps, or sometimes grasshoppers. They cling to the host animal and lay eggs between the segments of their abdomen. The hatching larvae then eat their way into the abdomen of the host animal, reside there and feed on the insides of the host until it is hollow. The larvae overwinter in the host insects. Some species, such as Conops flavipes (the most common species of the genus Conops) live in the nests of bees and bumblebees where their... | | |
| | Common to all wasps is the black-and-yellow warning colour of the body. The Vespinae live in states or parasitically as so called cuckoo wasps. Adult Vespinae mainly feed on small parts of dead or living animals, from insects, pollen, plant juices and from nectars. Their larvae are mainly fed on animal meat.

| Queens overwinter. They appear in March or April. Bombus pascuorum nest both above ground (old birds’ nests) and below ground (abandoned mice nests). The bees use moss, grass and animal hairs to construct a hollow sphere inside the nest. The interior of the hollow sphere is sealed with wax. The queen then forms a small tub of wax, puts pollen in it and then lays 5 to 15 eggs on the pollen. It also builds a second, slightly larger...
...ms a small tub of wax, puts pollen in it and then lays 5 to 15 eggs on the pollen. It also builds a second, slightly larger vessel for nectar (for food on rainy days) . In the period up to August the population of the colony grows from 60 to 150 animals. During the months of September and October the colony (with the exception of the queen) dies. | | |

The Common green bottle fly larvae are considered useful as they are used as fishing bait, animal feed and today (once again) in the treatment of wounds.

| | ...s sylvarum feed on nectar and pollen from a variety of plants. The flight period of queens begins in April, (that of the young Bombus sylvarum in July) and ends in late October. A colony comprises 80 to 100 insects. The nests are built in small animal burrows (mice holes). | | |
| | ... the blood-sucking insects. They feed on nectar or water. While the Nematocera have a bad reputation amongst humans because their bites can be painful and can cause allergies and transmit germs, the crane fly (larval stage) is regarded as a useful animal, because the diet and elimination behaviour of the larvae help to improve the soil. | | |
| | The larvae of flesh flies are known as maggots. In the first stage of their development they breathe through their skin. However from the third larval stage on, they use their tracheal system. Maggots feed on animal substrates, some also on carrion. Others are parasitoids and live on earthworms, snails, scorpions, cockroaches, beetles and cicadas. | | |
| | The common yellow dung fly’s habitat of preference is animal pastures, where it can be found on dung heaps. It is also encountered in gardens, where it feeds on compost. The adult flies feed on nectar from flowers or on the body fluids of small insects. | | |
